Technical Field
[0001] The utility model relates to the technical field of fire detection equipment, and more specifically to a fire smoke exhaust window area detection device. Background Art
[0002] Fire smoke exhaust refers to the exhaust of smoke, heat and toxic gases through fire equipment to protect the lives of people, reduce casualties and property losses. In buildings, electric fire smoke exhaust windows are one of the common smoke exhaust equipment. This type of window is generally installed above the ceiling of the building. It means that there is only one window in a pane. Generally speaking, the area of a single window is about 1.44 square meters. The installation methods of single fire smoke exhaust windows installed on buildings can be divided into two types: flat opening and horizontal push.
[0003] When the inspection company personnel accept the fire-fighting equipment, it is necessary to inspect the actual installation area of the fire smoke exhaust windows to ensure that all smoke exhaust windows meet the design standards, and to provide feedback and reinstall unqualified smoke exhaust windows to ensure the personal safety of the residents. During the actual inspection process, the following problems exist: First, due to the large number of smoke exhaust windows above the building, the existing inspection components such as tape measures need to measure each smoke exhaust window one by one, which is labor-intensive and has low measurement and inspection efficiency; second, when the existing manual handheld tape measures and other inspection components are used to inspect the area of the smoke exhaust windows, due to operational reasons such as the placement direction, the inspection accuracy is not high enough, and it is easy to have a large deviation between the measured calculation value and the actual area. Utility Model Content
[0004] The purpose of the utility model is to provide a fire smoke exhaust window area detection device, which can simultaneously detect multiple smoke exhaust windows at one time, thereby improving the detection efficiency. At the same time, limiting components such as a positioning top plate and a liquid level are designed. Compared with manual measurement, the detection accuracy is higher.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A fire smoke exhaust window area detection device comprises a plurality of rows of fire smoke exhaust windows arranged at intervals in a transverse direction above the ceiling of a building, a detection device is arranged on the outer side of the opening end of the fire smoke exhaust window, the detection device comprises a base plate, driving wheels are arranged on both sides of the front and rear ends of the base plate, a lifting cylinder is arranged at the middle position of the upper surface of the base plate, a control box is arranged on one side of the upper surface of the base plate and a mobile power supply box is arranged on the other side, a lifting plate is connected to the telescopic section at the upper end of the lifting cylinder and clamps are arranged forward at both ends of the outer side of the lifting plate, a transverse bracket is fixedly clamped in the area between the front ends of the clamps by bolts, a plurality of area detection components are arranged at equal intervals on the lower surface of the bracket, and a liquid level is installed at the position between the middle ends of the clamps.
[0007] As a further optimization of this solution, the area detection component includes a mounting plate and a rotating seat. The mounting plate is connected to the lower surface of the bracket through two side struts. The non-rotating part of the outer periphery of the rotating seat is embedded in the center position of the mounting plate, and a four-way surrounding laser rangefinder probe is provided on the outer side surface of the lower end of the rotating part inside the rotating seat. Among them, the upper end of the rotating part of the rotating seat located at the center position of the bracket is drivingly connected to the output shaft of the driving motor. The driving motor is installed on the upper surface of the bracket. A steering identification arrow is provided on the side surface of the upper end of the rotating part of the rotating seat. The laser rangefinder probe, the driving motor, and the lifting cylinder are all connected to the control box through wires.
[0008] As a further optimization of this solution, a positioning top plate is provided in front of the side surface of the bottom plate. The positioning top plate is pressed tightly against the inner side frame of the fire smoke exhaust window. Both ends of the positioning top plate are connected to the side surface of the bottom plate through telescopic connecting rods, and a spring telescopic ejector rod is also connected between the side surface of the bottom plate between the telescopic connecting rods and the positioning top plate. A transmission belt is provided below the bracket, and the transmission belt is drivingly connected to the rotating parts of all rotating seats.
[0009] As a further optimization of this solution, the four-way surrounding laser rangefinder probe descends through a lifting plate and sinks into the interior of the window of each fire smoke exhaust window. The bottom plate moves on the side surfaces of different fire smoke exhaust windows through traveling wheels.
[0010] As a further optimization of this solution, the control box is connected to the mobile power supply box through wires. The horizontal length of the bracket is at least greater than the length of two fire smoke exhaust windows.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the present utility model, by setting a movable detection device structure, it can move outside several rows of horizontally spaced fire smoke exhaust windows, facilitating continuous area detection work for multiple fire smoke exhaust windows. At the same time, a special area detection component is designed. Through the four-way surrounding laser rangefinder probe, the length and width data of each fire smoke exhaust window are respectively detected. The area data is calculated through the control box. By setting different numbers of area detection components, multiple smoke exhaust windows can be detected simultaneously at one time, improving the detection efficiency.
[0013] In the present utility model, first, a laser rangefinder is used instead of traditional measuring tools such as a tape measure. Secondly, the levelness of the bracket is monitored through a liquid level gauge, and the parallelism between the bracket and the fire smoke exhaust window is limited through the positioning top plate. Compared with manual measurement, the detection accuracy is higher, and the obtained area data is more reliable. Description of the Drawings

Specific embodiments
[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the utility model easy to understand, the present utility model will be further described below with reference to specific drawings.
[0021] In order to solve the problems that in the existing situation, due to the large number of smoke exhaust windows above the building, existing detection components such as tape measures need to measure each smoke exhaust window one by one, resulting in a large labor intensity, low measurement and detection work efficiency, and when using existing manual hand-held detection components such as tape measures to accept the area of the smoke exhaust window, due to reasons such as the operation of placing and positioning directions, the detection accuracy is not high enough, and there is a large deviation between the measured and calculated value and the actual area, as Figure 1 shown, the present application includes a number of rows of horizontally spaced fire smoke exhaust windows 1 arranged above the ceiling of the building, and a detection device is provided outside the opening end of the fire smoke exhaust window 1;
[0022] As Figure 2As shown in the figure, the detection device includes a bottom plate 2. Traveling wheels 3 are provided on both sides of the front and rear ends of the bottom plate 2. A lifting cylinder 4 is provided at the middle position of the upper surface of the bottom plate 2. A control box 6 is provided on one side of the upper surface of the bottom plate 2 and a mobile power supply box 7 is provided on the other side. The telescopic section at the upper end of the lifting cylinder 4 is connected to a lifting plate 5, and clamping plates 8 are provided forward at both outer ends of the lifting plate 5. A horizontal support 10 is fixedly clamped between the front ends of the clamping plates 8 by bolts. A number of area detection components are equidistantly spaced on the lower surface of the support 10. A liquid level gauge 9 is installed between the middle ends of the clamping plates 10;
[0023] As Figure 3 shown in the figure, the area detection component includes a mounting plate 13 and a rotating seat 15. The mounting plate 13 is connected to the lower surface of the support 10 through columns on both sides. The non-rotating part of the periphery of the rotating seat 15 is embedded in the central position of the mounting plate 13, and four-directionally surrounding laser rangefinder probes 16 are provided on the outer side of the lower end of the rotating part inside the rotating seat 15. Among them, the upper end of the rotating part of the rotating seat 15 located at the central position of the support 10 is drivingly connected to the output shaft of a driving motor 13. The driving motor 13 is installed on the upper surface of the support 10. A steering identification arrow 14 is provided on the side of the upper end of the rotating part of the rotating seat 15. The laser rangefinder probes 16, the driving motor 12, and the lifting cylinder 4 are all connected to the control box 6 through a circuit 11;
[0024] As Figure 4 shown in the figure, a positioning top plate 17 is provided in front of the side surface of the bottom plate 2.

[0025] Specifically, during actual use, the tester pushes the area detection device to one side of at least three consecutive fire smoke exhaust windows 1 through the driving wheels 3, adjusts the direction of the bottom plate 2 so that the positioning top plate 17 abuts tightly against the inner frame of the fire smoke exhaust window 1. At the same time, the outer end of the clamping plate 8 extends above the window area of the fire smoke exhaust window 1. The lifting cylinder 4 is started to work through the control box 6, driving the support 10 to descend, and sinking the four-directionally surrounded laser rangefinder probe 16 into the window interior of each fire smoke exhaust window 1. Observe the liquid level gauge 9 at the final position to ensure that the levelness of the support 10 meets the detection requirements. Then, start all the laser rangefinder probes 16 to work through the control box 6 to obtain a set of measurement data of three fire smoke exhaust windows 1. Then start the drive motor 12 to drive the four-directionally surrounded laser rangefinder probe 16 to rotate 45 degrees, 90 degrees, and 135 degrees, and continue to obtain three other sets of measurement data of the three fire smoke exhaust windows 1. Calculate the average value through the control box 6 to obtain the area data of each fire smoke exhaust window 1. During the process, the rotation direction position can be observed through the steering identification arrow 14, and continue to push the bottom plate 2 to detect the subsequent fire smoke exhaust windows 1.
